When hubby and I were dating, he used to use this term with me all the time. "You need to manage your expectations" everytime someone did something that I thought was wrong or not what I would do. And I hated hearing it. So much so that I pretty much banned it from his vocabulary.
But it's come back to haunt me...see...it's a problem of mine. I have extremely high expectations of the people in my life. I guess I hold myself up to (what I think) is a pretty high standard and so I expect the same of others. And when they don't reach that, I get disappointed in them. And to some degree angry with them. After his "manage your expecations" speech usually comes the "why are you surprised?" speech where he goes over how people do not change and I need to stop expecting more from people than they are willing to give.
So I'm working on this.
I'm a work in progress.
This is going to be a lot of work.
